net/mlx5: Use recovery timeout on sync reset flow

Browse Source 
[ Upstream commit dfad99750c0f83b0242572a573afa2c055f85b36 ]

Use the same timeout for sync reset flow and health recovery flow, since
the former involves driver's recovery from firmware reset, which is
similar to health recovery. Otherwise, in some cases, such as a firmware
upgrade on the DPU, the firmware pre-init bit may not be ready within
current timeout and the driver will abort loading back after reset.
